Heat Pump Quiz

What are the two main types of heat pump?

• Air source heat pump and Ground source heat pump

• Water source heat pump and Solar heat pump

• Electric heat pump and Gas heat pump

• Oil heat pump and Biomass heat pump

What are the working principles of a heat pump?

• A water pump moves water from a lower level to a higher level through the application of energy.

• Refrigerant liquid is warmed by outside air and evaporates to a gas, then the gaseous refrigerant is compressed and its temperature increases which then passes through your cylinder and warms the vessel. The gas then cools and begins to condense to a liquid due to sudden drop in refrigerant pressure.

• Heat is generated by burning fossil fuels and then transferred to the property.

• Solar panels collect heat from the sun and transfer it to the property.

What is a refrigerant?

• A substance or mixture, usually a fluid, used in a heat pump and refrigerant cycle. In most cycles it undergoes phase transition from a liquid to a gas and back again.

• A solid material that absorbs heat and releases it slowly.

• A type of insulation used in heat pumps.

• A device that measures temperature changes.

What are the two temperature scales used within plumbing systems?

• Kelvin and Celsius

• Fahrenheit and Rankine

• Kelvin and Fahrenheit

• Celsius and Rankine

What is the general rule with regards to heat transfer?

• Heat moves from the warmer spaces to the cooler spaces

• Heat moves from the cooler spaces to the warmer spaces

• Heat remains constant in all spaces

• Heat moves randomly between spaces

What is the role of a compressor in a heat pump?

• It compresses the refrigerant causing the gas to heat up

• It cools down the refrigerant causing the gas to cool down

• It circulates the refrigerant without changing its temperature

• It filters the refrigerant to remove impurities

What is the energy efficiency of an A rated condensing gas boiler?

• 95% (for every 1kw gas input you will receive 0.95kw heat input)

• 85% (for every 1kw gas input you will receive 0.85kw heat input)

• 75% (for every 1kw gas input you will receive 0.75kw heat input)

• 65% (for every 1kw gas input you will receive 0.65kw heat input)

What is absolute zero in both Kelvin and Celsius temperature scales?

• 0 K and -273 degrees Celsius

• 0 K and -100 degrees Celsius

• 0 K and -50 degrees Celsius

• 0 K and -200 degrees Celsius

How is the efficiency of an ASHP measured?

• Coefficient of performance (CoP)

• Energy efficiency ratio (EER)

• Seasonal energy efficiency ratio (SEER)

• Annual fuel utilization efficiency (AFUE)

What is the equation that determines the efficiency of an ASHP?

• The heat delivered out of the unit divided by the compressor power or heat delivered into it

• The heat delivered out of the unit multiplied by the compressor power or heat delivered into it

• The heat delivered out of the unit added to the compressor power or heat delivered into it

• The heat delivered out of the unit subtracted by the compressor power or heat delivered into it
